In a brutal and horrifying scene that viewers found pushed the boundaries of taste and decency for the show, Negan took a swing at Glenn and caved his skull in with his barbed-wired bat Lucille.
In an extreme close-up of the awful scene, the full extent of what Negan did to him was laid bare – with his eye popping out of his head.

In the US, the Parents Television Council has condemned the episode for its "graphic violence" and called for it to be removed from the air.

Tim Winter, the council's president, said: "Last night's season premiere of The Walking Dead was one of the most graphically violent shows we’ve ever seen on television.

“It’s not enough to ‘change the channel,’ as some people like to advocate, because cable subscribers – regardless of whether they want AMC or watch its programming – are still forced to subsidise violent content."
